  • Imperative: Programming with an explicit sequence of commands that update state.

  • Declarative: Programming by specifying the result you want, not how to get it.

  • Procedural: Imperative programming with procedure calls.

  • Functional (Applicative): Programming with function calls that avoid any global state.

  • Function-Level (Combinator): Programming with no variables at all.

  • Object-Oriented: Programming by defining objects that send messages to each other. Objects have their own internal (encapsulated) state and public interfaces. Object orientation can be:

    • Class-based: Objects get state and behavior based on membership in a class.

    • Prototype-based: Objects get behavior from a prototype object.

  • Event-Driven: Programming with emitters and listeners of asynchronous actions

SaaS: a method of software delivery and licensing in which software is accessed online via a subscription, rather than bought and installed on individual computers.

PaaS: a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications.

IaaS: Infrastructure as a service (IaaS) is a standardized, highly automated offering in which computing resources owned by a service provider, complemented by storage and networking capabilities, are offered to customers on demand. Resources are scalable and elastic in near real time and metered by use.
